Japanese Patent Laid-Open No. H06-211394

In a conventional heat exchanger fin, a plurality of through holes into which a heat exchanger tube is inserted are formed in a metal strip.

However, at present, a heat exchanger using a multi-groove flat tube has been developed. Fins for heat exchangers (hereinafter sometimes referred to as flat tube fins) using such flat tubes are shown in Figs. 18A and 18B.

In the flat tube pin 31, the cutout part 34 into which the flat tube 5 was inserted is formed in several positions, and the louver (louver) between the cutout part 34 and the cutout part 34 is formed. The plate-shaped part 36 in which 35 was formed is formed.

The notch 34 is formed only from one side of the width direction of the flat tube pin 31. Therefore, the plurality of plate-shaped portions 36 between the cutout portion 34 and the cutout portion 34 are connected by the connecting portion 38 extending along the longitudinal direction.

However, the metal strips (the cutouts 34 are formed but not cut to a predetermined length, hereinafter referred to simply as "metal strips") in the state before forming into a flat tube fin are used for the conventional heat exchanger. When conveyed by the conveying apparatus of the pin manufacturing apparatus, the following problem arises. That is, in the above flat tube pin, since one side of the pin is opened by the cutout portion 34, the metal strip is transferred by the feed pin 32 inserted into the cutout portion 34. There is a problem in that a bias occurs in the transfer of the metal strip, and the feed accuracy is considerably worsened.

The present invention has been made to solve the above problem, and an object thereof is to provide a conveying apparatus for reliably conveying a metal strip of a flat tube fin.

According to one embodiment of the present invention, when manufacturing a flat tube pin having a cutout portion into which a flat tube used for heat exchange is inserted, from one side in the width direction to another side, A conveying device is provided for conveying a metal strip after forming a cutout and before cutting to a predetermined length, the conveying device having a metal strip placed on an upper surface thereof and extending in a conveying direction of the metal strip from an upper surface to a lower surface.

By this structure, even when there exists the conveyance pin 32 which does not protrude below only by the pressing force of the spring 70, the conveyance pin 32 can be forcibly pushed down.

First embodiment of the guide portion

5 is a plan view useful for explaining the transfer pin and the guide portion, and FIG. 6 is a front view seen from the front in the transport direction.

According to the present invention, in order to transfer the metal strip 49 used for the flat tube pin, the transfer of the metal strip is guided by contacting the side opposite to the opening direction of the cutout 34 of the metal strip 49. Guide portion 84 is provided.

In the embodiment shown in FIGS. 5 and 6, the front end of each conveying pin 32 is configured to branch into two, that is, the guide portion 84 and the conveying portion 82. The guide part 84 and the conveyance part 82 are provided in series along the width direction orthogonal to a conveyance direction. In such a configuration, since the front end of the feed pin 32 is bifurcated only when the feed pin 32 is viewed from the front in the feed direction, the guide portion is shown in FIGS. 2 and 4, which are side views. Can't see 84.

In this embodiment, when the transfer pin 32 is raised, the transfer portion 82 enters the cutout portion 34 of the metal strip 49, and the guide portion 84 is opposite to the opening direction of the cutout portion 34. Contact with the sides of the. In other words, the connecting portion 38 of the metal strip 49 is held in the width direction by the guide portion 84 and the transfer portion 82.

By moving the movable body 55, the transfer pin 32 is moved with the movable body 55 in the conveyance direction. This means that the conveying portion 82 pulls the metal strip 49 in the conveying direction, and the guide portion 84 can always support the side of the metal strip 49 during the conveying. In this way, the bias of the metal strip 49 can be prevented during the transfer, and the metal strip 49 can be accurately conveyed.

7 and 8 show that the front end of the transfer pin 32 is bifurcated, that is, branched into the guide portion 84 and the transfer portion 82, and a plurality of metal strips 49 are arranged in the width direction. An example of a "multiple tool setting" is conveyed at the same time.

In the example of the multiple setting shown in FIG. 7, the plurality of metal strips 49 are in an aligned arrangement with the opening directions of all cutouts 34 facing in the same direction. In this case, the feed pins 32 are arranged so as to correspond to the respective metal strips 49 so that the front ends of the feed pins 32 bifurcate to form the guide portion 84 and the feed portion 82. Thereby, each metal strip 49 can be conveyed in a conveyance direction.

As shown in FIG. 8, the some conveyance pin 32 is arrange | positioned along the width direction with respect to the one movable body 55 extended in the width direction. By providing the transfer pins 32 corresponding to the respective metal strips 49 on the respective movable bodies 55, the vertical movement and the transfer speed of the respective transfer pins 32 can be synchronized.

9 and 10 show another example of multiple settings.

In FIG. 9, as in FIG. 7, a plurality of metal strips 49 are arranged in the width direction so that the plurality of metal strips 49 are simultaneously transferred, but the opening direction of each cutout 34 alternates in the width direction. It is arranged. Here, an example in the case where three metal strips 49 are arranged in the width direction is shown, with the opening of the metal strip 49 arranged on the left side facing the opening of the metal strip 49 arranged in the center. Doing. The connection part 38 of the metal strip 49 arrange | positioned at the center and the connection part 38 of the metal strip 49 arrange | positioned at the right side face each other.

If the metal strips 49 are arranged opposite to each other in this manner, it is possible to use a transfer pin 32 which is commonly used for the two metal strips 49.

That is, as shown in FIG. 10, the front end of the conveyance pin 32 is formed so that it may branch into three branches, the projection part of the both ends of the width direction will be the conveyance part 82, and the center projection part will be a guide part. (84).

Both side surfaces of the guide portion 84 in the width direction are in contact with the side surfaces of the connecting portion 38 of the metal strip 49 located on both sides in the width direction of the guide portion 84. The widthwise spacing between the two metal strips 49 in which the connecting portions 38 face each other is such that both sides of the width direction of the guide portion 84 are connected to the connecting portions 38 of the respective metal strips 49. It is necessary to set the width to allow the guide portion 84 to enter into the gap in contact with the side surface of the.

Since only three metal strips 49 are shown here, the left metal strip 49 uses only the transfer portion 82 and the center guide portion 84 on the left side of the three-provided transfer pin 32. Doing. In this case, for a metal strip 49 which cannot use a transfer pin common to other metal strips 49, a transfer pin 32 having two front ends as shown in FIG. 6 can be used.

As such, in a case of multiple settings in which metal strips face each other, since the guide portion 84 can be shared by two metal strips 49, the number of parts can be reduced and each metal strip 49 The gap in the width direction between them can be narrowed, which contributes to the miniaturization of the entire apparatus.

As mentioned above, the some conveyance pin 32 is arrange | positioned along the width direction with respect to the one movable body 55 extended in the width direction. By providing the transfer pins 32 corresponding to the respective metal strips 49 on one movable body 55, it is possible to synchronize the vertical movement and the transfer speed of each transfer pin 32.

As described above, each guide pin 86 contacts the side opposite to the opening direction of the cutout 34 of the metal strip to guide the transfer of the metal strip 49. The guide part 86 of this embodiment moves in the feed direction A in synchronism with the feed pin 32.

Each guide pin 86 is arranged to be movable up and down in the through hole 90 formed in the movable body 55. The lower end of the guide pin 86 protrudes beyond the lower surface of the movable body 55, and a large diameter portion 91 having a larger diameter than the guide pin 86 is formed in the middle portion of the through hole 90 of the movable body 55. The large diameter portion 91 is provided with a spring 94 that is a pressing means for pressing the guide pin 86 downward. A flange portion 96 formed in a shape having a diameter substantially the same as that of the large diameter portion 91 is provided at a portion corresponding to the large diameter portion 91 of the guide pin 86. A spring 94 having a downward pressing force is disposed between the upper surface of the flange portion 96 and the top surface of the large diameter portion 91.

Such a guide pin 86 is provided on the movable body 55 in the same structure as the transfer pin 32. When the movable body 55 is not located on the plate cam 74, the guide pins 86 The lower end projects downward by the spring 70, and the front end of the guide pin 86 is located below the metal strip 49. When the movable body 55 is moved above the plate cam 74, the lower end of the guide pin 86 protruding beyond the lower surface of the movable body 55 contacts the plate cam 74, so that the guide pin 86 is raised. And the side opposite to the opening direction of the cutout portion 34 of the metal strip 49.

In this embodiment, the position of the guide pin 86 and the transfer pin 32 is arrange | positioned at the position displaced along the conveyance direction, not aligned along the width direction.

This is because the pressing means in the form of springs 70 and 94 for pressing the transfer pin 32 and the guide pin 86 downward is arranged inside the movable body 55, thereby aligning the pressing means in the width direction. This is because it is difficult to secure enough space.

FIG. 13 shows that a plurality of metal strips 49 are arranged in the width direction when the guide pin 86 is provided on the movable body 55 apart from the transfer pin 32. 49 shows an example of multiple settings being transferred simultaneously.

In the example of the multiple setting of FIG. 13, the plurality of metal strips 49 are in an arrangement state in which the opening directions of the cutout portions 34 all face the same direction. In this case, a pair of guide pins 86 and a transfer pin 32 can be used for each metal strip 49.

In other words, since an example is shown in which three metal strips 49 are arranged in the width direction, three pairs of guide pins 86 and a transfer pin 32 are provided.

These some transfer pin 32 and the guide pin 86 are arrange | positioned in the width direction with respect to each movable body 55 extended in the width direction (not shown). By installing the transfer pins 32 and the guide pins 86 corresponding to the respective metal strips 49 on the respective moving bodies 55, the respective transfer pins 32 and the respective guide pins 86 Up and down movement and feed speed can be synchronized.

14 shows another example of multiple settings.

FIG. 14 shows an example in which a plurality of metal strips 49 are arranged in the width direction, and the opening directions of the respective cutouts 34 are alternately arranged in the width direction. Here, an example in the case where three metal strips 49 are arranged in the width direction is shown, where the opening direction of the metal strip 49 arranged on the left side is the opening direction of the metal strip 49 arranged in the center and Face to face. The connection part 38 of the metal strip 49 arrange | positioned at the center and the connection part 38 of the metal strip 49 arrange | positioned at the right side face each other.

As described above, when the metal strips 49 are disposed to face each other, guide pins 86 commonly used for the two metal strips 49 may be used.

Here, two guide pins 86 are provided for the three metal strips 49. Among these, the guide pin 86 located on the right side has both sides of the side surface of the connection part 38 side of the metal strip 49 of the right side, and the side surface of the connection part 38 side of the center metal strip, and both side surfaces of the width direction. It is arrange | positioned at the position which contacts. That is, the metal strip 49 on the right side and the metal strip 49 on the center are guided by one common guide pin 86. One guide pin 86 is arranged with respect to the metal strip 49 on the left side. Since it is difficult to provide the conveyance pin 32 and the guide pin 86 adjacently in the width direction, the conveyance pin 32 and the guide pin 86 are arrange | positioned in the position displaced in the conveyance direction.

When the metal strips 49 are disposed so as to face each other in this way, the widthwise spacing between the two metal strips 49 in which the connecting portions 38 face each other is the amount of the width in the width direction of the guide pin 86. It is necessary to set the width to allow the guide pin 86 to enter into the gap in the state where the side is in contact with the side of the connection portion 38 side of each metal strip 49.

As such, in the case of multiple settings in which the metal strips face each other, the guide pins 86 can be shared by the two metal strips 49, thereby reducing the number of parts and between each metal strip 49. It is possible to narrow the interval in the width direction, which contributes to the miniaturization of the entire apparatus.

As described above, the plurality of transfer pins 32 and the plurality of guide pins 86 are disposed in the width direction on one movable body 55 extending in the width direction (not shown). By providing the transfer pins 32 corresponding to the respective metal strips 49 on the respective movable bodies 55, the vertical movement and the transfer speed of the respective transfer pins 32 can be synchronized.

Third embodiment of the guide part

Another embodiment of the guide portion is shown in FIG. 15.

In this embodiment, the guide portion 98 is a fixed wall portion and is provided so as to always be in contact with the side opposite to the opening direction of the cutout portion 34 of the moving metal strip 49. However, when the fixed wall portion is used as the guide portion 98, since a resistance is generated between the side of the moving metal strip 49 and the guide portion 98, the guide portion movable in the conveying direction as described above is preferable. I think.

The metal strips conveyed in the conveying direction by the conveying device according to the present invention are not limited to those of the configuration shown in FIG. 1, but may have other configurations, such as different numbers, positions, and shapes of the louvers 35 and / or openings 37. It is also possible to employ.

Although the present invention has been described with reference to preferred embodiments, the present invention is not limited to the above embodiments, and various modifications may be made without departing from the spirit of the present invention.
